Erik Prince allegedly helped arrange a 2017 meeting in the Seychelles islands meant to set up a back channel of communication between the Trump camp and Russia.

The latest twist in special counsel Robert Mueller’s probe puts the spotlight on a shady associate of President Trump who is no stranger to controversy.

Erik Prince, the brother of Trump’s Education secretary Betsy DeVos, was a deep-pocketed donor to Trump’s campaign and was close with former White House strategist Stephen Bannon.

But until this week, he has remained a relatively obscure background character in the intricate web that is the Trump world.

That changed Wednesday as a witness has reportedly testified that Prince helped arrange a 2017 meeting in the Seychelles islands meant to set up a back channel of communication between the Trump camp and Russia.

That revelation counters testimony Prince made before the house Intelligence Committee last year.

On Thursday, liberal groups including the Campaign for Accountability called on the House to refer Prince to the Department of Justice for an investigation into his activities.

“Erik Prince’s testimony, never credible on its face, is directly contradicted by numerous press reports,” the nonprofit’s director Daniel Stevens said in a statement. “If, as President Trump claims, there was no collusion, then there is no reason for so many people who worked to install Trump in the White House to lie to those investigating the election.”

Prince’s attendance at the Seychelles meeting was first reported by the Washington Post. He told the House panel that his meeting with a Kremlin-linked banker was pure chance.

George Nader, a Middle East specialist who like Prince has ties to the United Arab Emirates, was also in the Seychelles at the same time.

He is now cooperating with Mueller’s team, which is investigating possible ties between the Trump campaign and Kremlin-based election meddling.

Rep. Adam Schiff (D-Calif.) said that reports that Nader has told Mueller’s team the island rendezvous was an effort to set up clandestine communications with Russia is “obviously at odds with what we heard in the testimony at the House Intelligence Committee” from Prince.

All of which spells possible trouble for Prince, a former Navy SEAL and the heir to an auto parts fortune.

The 48-year-old first gained national attention after he founded the private military company Blackwater in 1997.

The firm gained notoriety following the invasions of Iraq and Afghanistan. Its mercenaries were used to guard bases and U.S. officials.

Blackwater made millions — and became ensnared in controversy as civil suits, investigations, bribery accusations and a quartet of contractors working for the company were convicted of killing several unarmed Iraqi civilians, including children.

Prince sold the company in 2010 and began doing private security work for the United Arab Emirates and other royalty in the Middle East.
